Correlated Charge Transport in an Organic Coulomb Glass

Advanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Polymerization‐Charge Controlled Threshold Voltage Tunability in Organic Electrochemical Transistors

Advanced Electronic Materials
Threshold voltage (Vth) is an important parameter in organic electrochemical transistors (OECTs), which are widely used in bio‐sensing and neuromorphic applications. In bio‐sensors, low Vth, consequently near zero gate voltage at transconductance maximum,
